The GRR-RIPPER MAX by Microjig represents the highest standard in precision and safety for woodworking. Engineered for serious craftsmen, it offers unmatched control with advanced features, including the new SafeRip Kit, 1/8″ and 1/4″ Legs for intricate cuts, and comprehensive warranties for peace of mind.

Introducing the GRR-RIPPER MAX by Microjig, your Ultimate Companion in the Workshop.

Step into the world of precision woodworking with the GRR-RIPPER MAX, the latest innovation from Microjig, meticulously designed to provide ultimate control, safety, and versatility. Whether you’re a seasoned professional or a dedicated hobbyist, the GRR-RIPPER MAX offers features that elevate your craft to new heights, ensuring every cut is safe, accurate, and effortless.

At the core of the GRR-RIPPER MAX is its revolutionary Triple-Directional Force system, which delivers stability from every angle. This ensures that your workpiece stays secure and aligned throughout the cut. The downward pressure stabilizes your material, while inward pressure keeps it tight against the fence, virtually eliminating the risk of dangerous kickback. Forward pressure feeds your stock consistently through the blade, preventing burning and ensuring a clean, smooth finish every time.

  • The GRR-RIPPER MAX is equipped with specialized 1/8″ and 1/4″ Legs, making it the perfect tool for handling small parts and performing intricate cuts on the table saw. Whether you’re crafting edge banding, models, or decorative inlays, these legs allow you to rip thin strips with absolute precision, safety, and repeatability. This capability makes the GRR-RIPPER MAX indispensable for projects requiring detailed work.
  • The GRR-RIPPER MAX offers more than basic functionality. It’s a complete system. Inside the box, you’ll find the GRR-RIPPER PRO alongside every accessory Microjig produces. From the Stabilizing Plate, which offers 250% more stabilizing surface, to the Gravity Heel Kit with dynamic sacrificial heels that prevent tearout, every component is engineered to maximize your safety and efficiency.
  • One of the standout features of the GRR-RIPPER MAX is the SafeRip Kit, designed to prevent blade contact with the pushblock’s Center Leg during rip cuts. This kit guides the Center Leg setting, ensuring it’s always in the correct position, reducing the risk of accidental cuts. The SafeRip Kit provides an additional layer of safety and makes your setups quicker and more precise.
  • The GRR-RIPPER MAX isn’t confined to just one tool in your shop. It’s designed to work seamlessly across a variety of woodworking machines. On the table saw, it acts as a moving blade guard, offering unparalleled protection while allowing you to rip thin strips down to with complete control. On the router table, its powerful grip ensures command over your stock, whether you’re using the fence or freehand routing. When used on the jointer, the GRR-RIPPER’s Green GRR-RIP,  material provides the traction you need for safe and effective face-jointing. Its ability to maintain a constant 90-degree angle on the band saw reduces blade drift, resulting in smoother, more accurate resawing.
  • Fully Adjustable for Any Task. Every aspect of the GRR-RIPPER MAX is designed with adaptability in mind. The Center Leg adjusts to accommodate varying material widths, allowing you to maintain control over both the keeper and off-cut sides of your workpiece. The Balance Support adjusts to match material thickness, keeping the GRR-RIPPER upright and square, while the Adjustable Spacer increases the gripping surface by 54%, giving you greater control over larger workpieces.

An Actual Nice Chair for a Decent Price. +2 for the Tool.
Color: Black Grey
Welp, My old chair finally broke, so It was time for a new one. I ended up coming across this chair here, and I couldn't really find anyone talking about it online. I decided to give it a shot since it was on a good sale for Christmas, going down to 99$. I'm going to be honest, I am pleasantly surprised. The cushioning for it is a little firm, but that is perfect for me. Its pretty average when it comes to office chairs, but having the added lower back support is a great touch. I have no complaints about it. The one thing that I am actually really happy about isn't on the chair. Don't get me wrong, over the week I have been using it, It has been nothing but great. That thing is the actual tool it came with. Its a basic Allen key, but the top of it is a molded handle instead of a "L" piece of metal. It made the already easy process of putting together this chair even better. Even after this chair has ran its course like all other chairs, I'm going to still use this tool. So yeah, I think 5 - stars pretty accurately describes how I feel about my chair.

Comfortable chair that works great for long hours
Color: Black
I’ve been using this office chair for a few days and it’s been very comfortable for working and longer desk sessions. The high back design and ergonomic support help maintain good posture, while the cushioning stays comfortable throughout the day. The chair feels sturdy and stable, and the 330 lb capacity gives it a solid, durable feel. It also rolls smoothly and quietly, which is nice when moving around the workspace without creating a lot of noise. Overall, it was easy to assemble, looks professional, and offers great value for the money.

Very Comfortable Ergonomic Chair - Great for Long Work Days!
Color: Black, Color: Black
I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support. What I like: • Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain. • Good lumbar support and adjustable height/armrests. • Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable). • Smooth rolling wheels and sturdy base. • Easy to assemble (took about 20 minutes). The mesh back breathes well and doesn’t get hot. It looks professional in my home office too. Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it. Would I buy it again? Yes, definitely.

Great if you're average height.
Color: Black
Comfortable for the price. The seat could be a bit better, but for a budget friendly ergonomic chair, it's well made and has helped a lot with my back pain caused by my previous desk chair. Assembly wasn't terribly difficult, though I did have one screw with damaged threads. Luckily they ship spare screws in the kit, so that was a non-issue. Rollers work great on my small rug and hard flooring and don't tend to tangle cords or cables too much. Size wise, works great for my frame (5 ft 6 in) but for someone more than a few inches taller than myself, you should probably look at another chair.

Great chair
Color: Black
I am very happy with my purchase. Easy to assemble but be aware your drill bits included with your set won't fit their screws. However, you can get a fair bit done with the drill and then use tool included to adjust. Super comfortable and exactly the right height for my desk. Highly recommend for quality exceeding price point.
